Leners Patent No. 97,'132, dated November 23, 1869.

IMPROVED STAIR-ROD.

The Schedule referred to in these Letters Patent and making part of the same.

Be it known thatI, JOSEF STUEHLER, of Brooklyn, in the county of Kings, and State of New York, have invented a new and .improved Stair-Rod Fastener; and I do hereby declare that the `following is a full,

clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part ot' this specification, in which- Figures l and 2 are longitudinal sections ot' my improved stair-rod fastener, showing two modifications of the same.

Similar letters of reference indicate corresponding parts. 1

lhis invention relates to a new stair-rod fastener, which is so constructed that the rod can be readily applied and removed, and securely retained in proper position.

The invention consists in forming a sliding springcap on one end oi' a hollow rod, the said cap serving to lock the rod to a pair ot' hooks, or their equivalents, which are fastened'in the stairs; thereby a simple and cheap rod and reliable fastening are produced.

A, inithe drawing, represents a tubular. or prismatic hollow stair-rod, made of suitable material and length.

At one end itv has a sliding cap, B, and at the oiher, a similar imitation cap, C, the latter being fixed to or formed on the rod.

The sliding cap O carries on its inside a longitudinal stein, 1), which projects into the rod, and which receives a spiral spring, a, around it, as shown.

The spring o is either fitted between the end of the cap and a cross-piece in the rod, as in lig. l, so that it has the tendency to push. the cap B out, or it is, as in tig. 2, fitted between a shoulder, o, on the inner end of the stem D, and a perforated plate, d, that closes the end of the hollow rod A, as shown, so that thereby said spring has the tendency to draw the said cap in.

lThe rod has one slot or aperture, j', where it is covered by the cap B, and even the latter must, when applied as in fig. 1 have a slot, g; i i

.lhe rod is to he fastened to two' hooks,s/crews, pins, or equivalent devices, E E', wliilrhfare fastenedfto the stairs. The hook'E ii'ts through a slot in the" rod, at or uearthe cap Cfand ther'the Vrod is-lnoved to bring the non-slotted part'under lthe hook. -f f The slots f and/g, fig. 1, are then,'/bypushing the cap B in, brought lin lille, which will allow the rod to be fitted over the hook E. The spring will then push the cap B out, and will lock it under the hook E, as in tig. 1.

The rod can be taken ot', when the cap'B is again pushed in, to bring the slots" j' and g in line. It is evident, that in this case, the hooks must point inward with their bills, because the spring draws the cap outward to lock it. In the case shown in fig. 2, the hooks point outward, because the spring draws the cap inward to look it. In fig. 2, the cap is represented without a slot, it being locked under the hook with its infiel-edge.

The rod is unlocked by drawing the capentirely away from under the hook. lhe stem may, by using large or other-.shaped springs, he dispensed with.

I am aware that spring-bearings, in hollow tips,-
